Hi Jeff,I am certain that the best midbass was NEVER in a corner horn. Every fold in the horn is a new resonance. Corner horns need many folds...In addition, if you are very "anal retentive" about phase alignment - how do you integrate a corner horn?...

Actually it was sad to hear potentially nice horn system wasted on mediocre music (at least that's what I heard at three different times I visited the room so it must have been a norm ) and grey sounding D-amps with "pumping " bass tubas. At least th...

[quote user="Romy the Cat"] In fact I do feel that
my MF and upperbass are very good integrated. But again, I might not know how
different it might be if it was otherwise. [/quote]
Exactly!
Some time ago I also thought my upper bass channel is ...

Have you considered the opportunity of raising your upper bass HP crossover? How high do you plan to use your mid bass horns? If your mid bass is comfortable playing up to 280hz (or whatever the right freq is), you can use your upper bass horn to p...

The idea of 360 degree radiation of sound has great intuitive appeal to me since I feel the best recordings are done with two omnidirectional microphones. The most precise reproduction of the musical event would seem to be: sounds enter microph...

Well, I didn't come so close to answer your question right.I saw a few from the German DIY scenery and for them it was like the return of Jesus, best sound on PlanetBut probably they are still deaf as usual, because the Frequency step ups are limited...

This makes a lot more of sense to me. I understood you wrongly and I believed that the product "as is" and a priori can be interesting as a whole. I think that the design is interesting for the horn implementation, the horn themselves (look quite sol...

[quote user="Thorsten"] First, the Lowther has ze wizzer cut off and has an Equalisation circuit to flatten ze upper midrange bump. Otherwise it is run fullrange, that is WITHOUT HIGHPASS OR LOWPASS. [/quote]
Probably this is why the Lowther sounded...

[quote user="haralanov"] Romy, the actual sound benefit of this 4-channel upper bass configuration, is rather in the type of sound presentation. The commonly used single upper bass horn (or direct radiator) sitting under the midrange horn, gives the ...

I note English Mfgrs tried low power ribbon Midrange horns in the 50's (Decca, Kelly & Quad also made one!).These were probably inspired by the hi pwr prewar? Klangfilm ribbon horn (would like to hear one of those!) But, after Peter Walker moved ...

somehow i missed that moment in macondo development when you introduced S3 as a low mid driver so this came as a surprise to me - what i remember is that you didn't write so favourably of S3 back in 2004 due to its ceramic magnet. but it's good t...

Disclaimer: I love listening to experienced people. However I do not do everything they say. I would like to hear them as it can direct me and save me some resources like time and money and make me think of things I have missed and ...

Why dont you use your midrange horn with the JBL from 600hz to 4800hz? I think it would have a fairly flat and good response and tt wont be beaming. It works with the tractrix 1000, I have done it before. I then tried my Radian 475be with JMLC1400 fr...

Not at all looking for suggestions on what to do but to share findings about the optimal use of the multicell midrange horns. For example, I see that Romy has played around with this horn and I am sure listened to it by itself. So what were the findi...

lately I've come to theorize that the horn midbass may be a contadictive dead end approach. The reason is that proper horn midbass (lets say 80 to 400Hz) will be a big one and present a few inherent "brick walls". It will physically shade the midrang...
|
|
I do agree even the bass-bin is not time-aligned to the MF horn, I think it's at least ~25cm far from the midrange horn but IMO as frequency goes up, time-alignment gets more critical. this alignment might look "unnecessary" with when midrange and tw...

Angelo, We should probably start a new thread to discuss horn construction in general, as this thread is about a specific aspect of that subject (driver to horn transition).To answer your question very quickly... As previously mentioned, I will ...

I have no idea what it is but it is something… Take a look:

It is 3 way horn loaded with external LF section, so far so good. Atop then have RAAL ribbon that ...

That "curl" beyond 350mm in your diagram is what the LeCleach profile is all about...drop it and it is not a LeCleach anymore (it is more or less Tractrix) and the benefits of that profile to do with the horns lower range are lost. Besides, a 1m dia...

Romy, if you have some spare diaphragm/VC assemblies for your S2 drivers, do the experiment I mentioned above (remove the outer layer of the VC) and we will talk about the inductance in terms of sound after you hear the results with your own ears... ...

Maybe the upper midrange horn became like a paper cone speaker. Best sound I ever made, and it looks like this. It had the same ring to it as the magical SABA fullrange speakers - made of paper. But below 500Hz, I must use solid wood. The Fanes are t...

Romy,
[quote user="Romy the Cat"] Remind you that horn
not only does that but it performs acoustic transformation gradually. [/quote]
Yes, I do
agree with you about that. From both theoretical and practical point of view it
is 100% true. But...

If there is one thing that I have learned in life, and heard many times, is that making a mistake is not a bad thing if you learn from it. In addition the lesson learned is just as valuable if you learned it from someone elses...

My string quartet have just spent 6 days recording haydn and being assaulted by nasty Genlecs.
